B4A Library Spinner Wheel - Vertical and Horizontal (24 June: new lib files in post #47)

It wraps the Vertical Spinner Wheel part of this Github project. Spin the wheel with a finger - up or down. The spinner is cyclic i.e it acts like a circular buffer.

Posting:
1. B4A project demonstrating the use of the Vertical Spinner Wheel - b4aAndroidSpinnerWheel.zip
2. Zipped files with the required library files (including nineoldandroids) - copy them to your additional library folder. Library files are in AndroidSpinnerWheel.zip

Please note: have added no code in the designer or in the B4A project to position the views - just plonked down and dragged them in the designer. Leaving positioning to those making use of this project.

I will add the Horizontal Spinner Wheel part of the project at some stage...

    'These variables can only be accessed from this module.

    Private vsw1, vsw2 As WheelVerticalView

    Dim cities() As String
End Sub

I am experiencing very strange behaviors in my App if I use this Spinner-Wheel Lib.

One of the reasons for the above error described in my previous post was because of the sequence of the commands given. For eg the following sequence should be followed or else I get the above error described in my previous post.

For eg. I assigned WheelVerticalView1.SelectedIndex before WheelVerticalView1.setupSpinnerWheel
B4X:
WheelVerticalView1.SpinnerItems = months
WheelVerticalView1.SelectedIndex = 1 
WheelVerticalView1.setupSpinnerWheel

The right way is
B4X:
WheelVerticalView1.SpinnerItems = months
WheelVerticalView1.setupSpinnerWheel   
WheelVerticalView1.SelectedIndex = 1

I don't know whether the error message was misleading or not.

I still get the same error message whenever WheelVerticalView fails

Now let me describe the core issue that I experience right now when I tested this lib. I have an activity and it has just one view placed on it via designer ie WheelVerticalView1. The below is the B4A code. The code itself is self explanatory with proper comments on it.

B4X:
#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
   
End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Private reqManager As DBRequestManager
    Private WheelVerticalView1 As WheelVerticalView
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Test")
    If FirstTime Then
        reqManager.Initialize(Me, Starter.RdcServerIP) ' The IP of the machine running JAVASERVER
    Else
        If reqManager.IsInitialized = False Then
            reqManager.Initialize(Me, Starter.RdcServerIP) ' The IP of the machine running JAVASERVER
        End If       
    End If       
   
    'The next sub works fine. It displays the Wheel perfectly.
    ' But if I comment this call to the Sub TestWheel from Activity Create aand call frrom some other place
    ' then  the app will Force quit abnormally
   
    'TestWheel  'Call TestWheel sub
   
    ' The app is supposed to fill the data in the WheelView from a Remote Table. So get the data from the Remote Table
    ' and fill the WheelView using the following Sub ie GetVehicleModels
    ' To test the problem, comment the above call to the Sub TestWheel and uncomment the next statement
    ' ie GetItemDetails
    '
    GetItemDetails  'This will not work.
   
End Sub

Sub TestWheel
    Dim months() As String
    months = Array As String("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December")
    WheelVerticalView1.SpinnerItems = months
    WheelVerticalView1.setupSpinnerWheel   
    WheelVerticalView1.SelectedIndex = 1   
End Sub

Sub Activity_Resume
    If reqManager.IsInitialized = False Then
        reqManager.Initialize(Me, Starter.RdcServerIP) ' The IP of the machine running JAVASERVER
    End If
End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Sub GetItemDetails
    Log("Log : Inside GetItemDetails")
   
    Dim cmd As DBCommand
    cmd.Initialize
    cmd.Name="GetItemDtls"
    Log("Log : About to execute reqmanager")
   
    ' If I have WheelView then the app WILL NOT EXECUTE BEYOND THIS POINT. It will raise the error
    ' If I   R E M O V E   the WheelView then it works fine and the JobDone is Executed   
   
    Try
        reqManager.ExecuteQuery(cmd, 0, "ItemDetailsList")
    Catch
        Msgbox("Could not establish connection with the server","Check Internet")
    End Try           
End Sub

Sub JobDone(Job As HttpJob)
    ProgressDialogHide
  If Job.Success = False Then
     Log("Error: " & Job.ErrorMessage)
  Else
    If Job.JobName = "DBRequest" Then
            reqManager.HandleJobAsync(Job, "ReqManager")
        End If
    End If
    Job.Release
End Sub

Sub ReqManager_Result(result As DBResult)
    Log("Log : Inside ReqManagerResult")
    reqManager.PrintTable(result)

    If result.Tag = "ItemDetailsList" Then
        Log("Log : Inside ReqManagerResult")
        AddData2WheelView(result)       
    End If
End Sub       

Sub AddData2WheelView(result As DBResult)
    Log("Log : Inside AddData2WheelView")

    'Actually here I am supposed to fill data to the WheelView. As the WheelView is not working and
    'to demonstrate the problem, I am calling the Sub TestWheel from here

    TestWheel
End Sub


I get the following error

** Activity (homepage) Pause, UserClosed = false **
** Activity (test) Create, isFirst = true **
Log : Inside GetItemDetails
Log : About to execute reqmanager

Resolved.

You need the following lines before you do anything with wheelview

WheelVerticalView1.SpinnerItems = Array As String()
WheelVerticalView1.setupSpinnerWheel

B4X:
Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Test")
    If FirstTime Then
        reqManager.Initialize(Me, Starter.RdcServerIP) ' The IP of the machine running JAVASERVER
    Else
        If reqManager.IsInitialized = False Then
            reqManager.Initialize(Me, Starter.RdcServerIP) ' The IP of the machine running JAVASERVER
        End If    
    End If    

    'The following lines are mandatory
    WheelVerticalView1.SpinnerItems = Array As String()
    WheelVerticalView1.setupSpinnerWheel

    GetItemDetails  

End Sub

Hi,

Is there a possibility to display the spinner contents Horizontally left aligned OR right aligned. ?
  • As of now the contents of the spinner appear center aligned
Is there a possibility to change the typeface of the spinner contents ?
  • As of now it is in Bold Typeface
Regards

The attached library files takes care of it (for the vertical spinner). Use it in your code as follows:
B4X:
vsw2.TextGravity = vsw2.GRAVITY_LEFT       'or GRAVITY_CENTER or GRAVITY_RIGHT
vsw2.TextTypeface = vsw2.TYPEFACE_NORMAL   'or TYPEFACE_BOLD or TYPEFACE_BOLD_ITALIC or TYPEFACE_ITALIC

Question for Johan Schoeman
Why with the joined project, WheelSpinner_Value_Changed doesn't work?
Thank you

I have an issue with
WheelHorizontalImageView1


got error android.content.res.Resources$NotFoundException: Resource ID #0x0
You should have 5 files in the /Objects/res/drawable folder of the B4A project. Do you have them?
divider_dark_gradient_horizontal.xml
icon.png
wheel_bg_hor.xml
wheel_bg_ver.xml
wheel_val.xml


You should also have one file in the /Object/res/values folder of the B4A project. Do you have it?
wheel__attrs.xml

If not, then the utility program that you have used to extract the zipped B4A project has removed the READ ONLY properties of these files. Make sure that once you have unzipped the B4A project that these files are set to READ ONLY before you run the B4A project for the first time else these files will be deleted when you compile the B4A code.

Yesterday I found that. and made a question to the forum.
because the compiler delete those files.

See the folder structure of the B4A project - you are missing resources from your project that should be in the /Objects/res folder of the B4A project and in all probability not set to READ ONLY when you compile the B4A project - they will be deleted during compilation if not set to READ ONLY or you will get the error if they were not there at all
